To qualify for the official limited edition Hacktoberfest shirt, you must register and then make four pull requests (PRs) between October 1-31 (in any time zone). PRs can be made to any public repo on GitHub, not only the ones with issues labeled Hacktoberfest. If a maintainer reports your pull request as spam or behavior not in line with the project’s code of conduct, you will be ineligible to participate. This year, the first 50,000 participants who successfully complete the challenge will earn a T-shirt. (Last year 46,088 earned a shirt!)
In line with Hacktoberfest value #2 (Quantity is fun, quality is key), here are examples of the PRs that we consider to be low-quality contributions (which we discourage). ● PRs that are automated (e.g. scripted opening PRs to remove whitespace/optimize images) ● PRs that are disruptive (e.g. taking someone else's branch/commits and making a PR) ● PRs that are regarded by a project maintainer as a hindrance vs. helping ● Something that's clearly an attempt to simply +1 your PR count for October ● Last but not least, one PR to fix a typo is fine. 5 PRs to remove a stray whitespace... not.
